Pfizer Dental Vaccine Being Discontinued

Recommended Posts

Permission to cross-post granted from Dr Carol of Grassmere Clinic in Nashville,



"For any adopters whose greyhounds (or other dogs) received the Pfizer dental

vaccine, you should know that it is being discontinued for lack of proof of

efficacy. It was originally granted conditional approval, pending proof of

efficacy, but that was not forthcoming.



Response from Pfizer Animal Health:


The USDA licensed the Porphyromonas Denticanis-Gulae-Salivosa Bacterin as a

conditionally licensed vaccine. Conditional vaccine licenses must be renewed by

the USDA Center for Veterinary Biologicals each year with disclosure of any new

efficacy and potency data and progress to a full license must be demonstrated.

Periodontal disease due to its complex, chronic, and progressive nature is a

challenging disease to study. Pfizer Anima l Health conducted an unprecedented

48 month field efficacy study intended to support the full licensure of this

product. Unfortunately the study did not demonstrate a vaccine effect in

vaccinates (as compared to controls) for either of the key efficacy variables

assessed (attachment loss and gingival bleeding index). The current conditional

license for this vaccine will lapse on April 6th 2011 (except in the state of

Minnesota where it lapses on April 2, 2011) and given that these results do not

support efficacy the only available course of action was to discontinue the




Anyone who has listened to me rant about vaccines has heard this before, but

I'll repeat again... please be VERY sure of the vaccine needs of your greyhounds

and DO NOT get vaccines that are unproven, unnecessary, and sometimes

potentially harmful to a breed that seems to have a delicate immune system to

begin with.



Drug companies h ave produced many different vaccines over the years, but the

fact is that the only "core" vaccines every dog needs are rabies and the

distemper/parvo vaccine.


ALL OTHER VACCINES ARE "FRINGE" VACCINES, and should only be accepted by you for

your greyhound if you are sure of their need, their efficacy, and their safety.

And, remember the distemper/parvo vaccine should only be given every 3 years,

NOT annually."


Don't be afraid to question - don't be afraid to say no.

Thank Dr. Carol for passing this on to us. She is always so good at putting information out to the adopters.

I'm glad to see this vaccine will soon be gone. Gracie had a severe reaction to it.

Sorry, I did not know that Carol was a Doctor. I would have never bothered her with the question about rattlesnakes.


I'm not Dr. Carol. I found this on another group I am on and shared it here since permission was granted to cross post. If I was Dr. Carol I would be more than happy to answer any questions you had, unfortunately I'm not.
